From the Tollway to the Trailways

E-470 is more than just a tollway. Over the last several years in conjunction with road widening projects, the Authority has built more than 12.5 miles of the High Plains Trail – which runs adjacent to the tollway – to provide better connections for people on foot and on bikes to existing trails in the east Denver-Metro area, including the Cherry Creek, Piney Creek, Happy Canyon, and C-470 Trails. In addition, E-470 also strives to partner with its member jurisdictions on trail projects in the region.

Current Trail Projects

  • The current phase of E-470 road widening will include an extension of the High Plains Trail from 26th to 64th Avenues and from 88th to 104th Avenues within Aurora and Adams County. The trail extension is expected to be complete by 2025.
  • E-470 (along with other municipalities) has partnered with Arapahoe County to help fund a pedestrian overpass to help facilitate safer crossings at Parker Road for people on foot. The overpass is the first phase of a project that will eventually connect the High Plains Trail to the Cherry Creek Trail in Arapahoe County. For project updates, please visit Arapahoe County‚Äôs website.

Future Trail Projects


  • E-470 will partner with the City of Aurora to build a multi-use path connecting the bike lane on Jewell Avenue to the High Plains Trail.
  • The Authority will team up with Adams County to extend the Platte River Trail through the Riverdale Bluffs Open Space. E-470 is contributing about $3 million for this 1.75-mile trail extension.
There are dedicated parking spaces for High Plains Trail users at the E-470 Administration building.
